SPECIFICATION formingpart of Letters Patent No. 620,162, dated February 28, 1899.

Application tiled J' une 27,1898. Serial No. 684,556. (No model.)

To a/ZZ whom it may con/cern:

Be it known that I, ALEXANDER N. MON- TEER, of Springfield, Greene county, Missouri, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification.

Myinvention relates to car-roofs, and is designed more particularly as an improvement on what is known as the Chicago car-roof patented by Hiram Aldridge on November l, 1881, and numbered 248,905, the object in this connection being to produce a roof embodying the best featuresl of said Chicago roof, together With additions to that particular roof which eliminate all chance of water obtaining access to the interior of the car through the ridge-line.

With this object in view the invention consists in certain novel and peculiar features of construction and combinations of parts, as will be hereinafter described and claimed, and in order that the invention may be fully understood I will proceed to describe it with reference to the accompanying drawings, in Which- Figure 1 represents a top plan View of a car provided with a roof embodying my invention. Fig. 2 is a cross-section taken on the line II of Fig. 1. Fig. represents a longitudinal section taken on thev line III III of Fig. 2. Fig. 4 represents a longitudinal section taken on the line IV IV of Fig. 2. Fig. represents a perspective view of one of the carlines.

In said drawings, 1 designates the upper horizontal sills of a car of the usual or any preferred construction, and 2 the rafters of the same.

3 designates a pair of parallel strips extending longitudinally from one end of the car to the other and secured upon the rafters.

4. designates the carlines which rest upon the rafters, said carlines being provided in their side edges with longitudinal grooves 5 to receive the side edges of the roof-plates 6, aid plates being of sheet metal or its equivaent. l

7 designates short Wood strips which rest upon the plates 6 at opposite sides of the ridge or apex of the roof, and 8 sheet-metal angle-plates seated upon the wood strips 7 and bridging the ridge-line of the roof, said plates also overlapping the upper edges of the roof-plates and fitting in the bifurcated upper ends 8 of the carlines. This disposition of the angle-plates holds them securely in position and obviates all chance of water leaking through the roof at the ridge-line, as happens when the ridge-pole of the Chicago roof, for instance, splits or cracks. Furthermore, the joint is still bridged and remains unbroken even if the carlines move apart a considerable distance. The wood ridge-strips 7 serve to hold the plates 8 snugly in the bifurcated ends of the carlines and obviate rattling or unnecessary play therein of said plates 8.

10 designates a ridge-strip which extends from end to end of the car and rests upon the carlines at the ridge or apex of the roof.

11 designates the roof-boards proper, and surmounting them at the apex or ridge of the roof is the running or foot board 12.

13 designates strips which extend from end to end of the car and rest upon the carlines,

being secured thereto by screws or equivalent means.

14. designates side and end boards which support the outer ends of the roof and are secured in position by means'of the stop-blocks 15, interposed between them at suitable intervals and the sides and ends of the car in order that the roof may be perfect-ly ventilated-that is to say, in order that air may circulate freely between the roof 11 and the water-tight roof, consisting of the carlines, the plates 6, the strips 7, and the angle-plates 8-and said blocks are provided with notches 16 in their inner edges to receive the outer edges of plates 6 to prevent said plates from sliding outward.

It will be seen that the provision of a liveair space between the upper and lower sections of the roof prevents the interior of the car from attaining as high a temperature as it otherwise would, and it is also clear that the arrangement of the parts 4., 6, 7, and 8, forming the lower section of the roof, absolutely prevents water from entering the car.

From the above description it will be apparent that I have produced a Ventilating water-tight car-roof which embodies the features of advantage enumerated in the statement of invention and which is simple, durable, and comparatively inexpensive, and, furthermore, a car-roof which can be applied IOC) and angle-plates bridging the ridge-line, overlappin g the upper edges of the roof-plates and fitting in the bifuroated upper ends of the oariines, substantially as described.

In testimony whereof I aiiix my signature in the presence of two Witnesses.

ALEXANDER N. MONTEER.
